IMPROVEMENT IN ERAFT ATTACHMENT$ FGR WAGONS.

Specification forming part of Letters Patent No. 131,248, datedSeptember 10, 1872.

To all whom it mag concern:

Be it known that I, W. P. BROWN, of Malta, in the county of Morgan andState of Ohio, have invented a new and valuable Improvement in DraftAttachment and I do hereby declare that the following is a full, clear,and exact description of the construction and operation of the same,reference being had to the annexed drawing making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure 1 of the drawing is a representation of a planview of myinvention. Fig. 2 and Fig. 3 are details. h

This invention has relation to certain improvements in the running-gearof wagons; and consists in the construction and novel arran gement ofdevices and parts whereby the draft is applied to the under side andnear the ends of the front axle, and is coupled directly to thesingle-trees, making it continuous from v one single-tree to the other.By means of said improvements the draft-power is distributed and appliedat points where it will have most effect and tend to lessen the labor ofthe horses. The tongue and whiffletree are entirely relieved of strain,the latter being used merely to support the single-trees.

My improvements make proper allowance for the changes of the line ofdraft occasioned by unequal pulling or from other causes, and enablesobstructions to be more readily overcome by the wheels.

Referring to the accompanying drawing, A represents the front axle of awagon. B B are the front wheels; 0, the hounds; D, the tongue E, thewhiffietree and F F, the single-trees. G G represent pulley'sheavcs,supported by means of brackets g, and journaled to and near either endof the axle A. H designates a chain, connecting together the twosingle-trees F F by being passed back underneath the axle and around thesheaves G G. The chain is also connected near either end to thewhiffletree, but in such a manner as to support the sin gle-trces andchain while allowin g the whiffletree to be always free from draft. Tothe back part of the axle is attached a loop, 6, to which is connectedthe chain H in such a manner as to have sufficient play to correspond tothe movement or vibrations of the whiffletree.

In drawing the load the power is applied directly to the axle. Theattachment of the chain being low, a lifting draft is provided and thelabor of the team lightened. The draft is also applied near the ends ofthe axle, and perfect control of the wheels obtained, enablingobstructions to be easily overcome.

In Fig. 2 of the drawing is shown a modification of my invention. Forthe sheaves G G bell-cranks I I are substituted. The couplings i i maybe either rods or chains. The operation of these devices issubstantially the same as those first described.

What I claim as my invention, and desire to secure by Letters Patent, is

The sheaves G and chain H, in combination with the front axle A,whiffletree E, and sin- 1 of two witnesses.
